Certainly not 15 years but maybe 5 years. We have seen IMO two developments, professional wardeccers and less open-minded, challenge-seeking new players.
We can’t get rid of wardecs in one or the other way because we allow corp assets in space, but CCP can ease the imbalance. Also I think the expectations regarding a fix has to be low because of the highsec selection bias towards PvP.
That is, if competent PvPers, FCs and corps would arise in highsec, they will leave highsec. Because if you are good at PvP, there is no reason to live in highsec. So what’s left are those not yet experienced in PvP and those not interested in PvP (exceptions excluded, as they are in minority).
A solution should address both groups. The “not yet” group needs to get breathing room to learn in their own pace, and the “not interested” needs to get the option to easily outsource the problem.
My proposal addresses both, groups without a structure can’t be aggressed but they can defend other structures on their own terms (learning). Groups with structures, can easily let others do the work without any formalism or extensive socializing (outsourcing).
Finally this can fail because the group of “not yet but willing” is too small in highsec, but let’s try. All the other proposals with winning objectives and war structures do not address the two groups properly, either by taking away the voluntary aspect of learners, or ignoring the fact that you can’t force people to PvP who do not want to.
